GASOLEN E-LAIVI P.

SPECIFICATION forming part of Letters Patent No. 635,456, dated October 24, 1899.

Application filed April 5 1899. Serial No. 711,819. (No model.)

T0 @ZZ whom t Hwy concern.:

Be it known that we, WILLIAM A. Woon and JOHN M. EDDY, residing at Eugene, in the county of Lane and State of Oregon, have invented certain new and useful Improvements in Gasolene-Lamps, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to gasolene-lamps.

The object of the invention is to produce a gasolene-lamp of simple construction in which the gasolene or similar fluid may be vaporized and mixed with air Without the necessity of heating and in which the vapor may be formed just before feeding to the burners.

Figure l is a partial central vertical section and partial elevation of a lamp embodying the principles of this invention. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3, Fig. 1. Y

A indicates the gas reservoir or chamber of a lamp, which is preferably a metallic shell with a cylindrical upper portion and a tapering or frusto-conical lower portion.

Inside the reservoir A there is a perforated developing vessel B, preferably also of frustoconical form and supported within the shell A by braces C or in other suitable manner. The perforated vessel B is substantially iilled with cotton-waste or similar light porous substance, (indicated by K.)

Above the top or cover A of the vessel A there is mounted a duid-supply tank D, which by pipe E communicates with the reservoir A through the cover thereof. The passage from vessel or tank D to reservoir A is controlled by a cock or valve F, which when opened permits a very small passage of liquid from vessel D.

The vessel D may be lled with gasolene through a tightly-fitting stopper Gr, and when valve F is opened the fluid Will pass drop by drop into the reservoir A, falling on the upper surface of the cotton-waste K in vessel B. The liquid percolates slowly through the waste and forms a gas which escapes from the top or perforated sides of the vessel B.

The top A is provided with a small opening, which is normally closed tightly by means of valve M. A spring N, operating on the valve-lever O, tends to close the valve.

The valve-lever O is connected, as by link P, with the lever R, which operates the cock or valve F. A chain or cord S may be connected to lever R, so that the cock F and valve M may be opened simultaneously by a pull on the cord or chain and will be closed by the spring N when the pull is released. The chain S may be fastened so as to hold the cock and valve in open position. When so held, the gasolene will drop down and become vaporized. At the same time one or more of the burners T, of the Welsbach or similar incandescent variety, should be lighted, and gas from reservoir A will pass through pipeV to said burner or burners. The lights may be turned out by the usual cocks W.

When the lamp is not lighted, cock F and valve V should be closed. When one or more of the burners is lighted, the carbureted-gas mixture,being heavier than air,will flow down into the pipe V and so to the burner, and cock F and valve M being opened a continuous su pply of carbureted-gas mixture will be formed and conveyed to the burner.

As the gasolene-vapor is heavier than air, the passage of such vapor or gas down to the -lower part of casing A tends to draw in air through valve M when said valve is open, and this draft also mixes the gas with air.

. The closing of the cock W cuts off the gassupply from the burners, and as the gas cannot then escape from reservoir A it is advisable also to shut olf the valve M and cock F when the burners are put out. There will then be no development of gas in the reservoir.

The bail Y, connected to ears Z, serves as a convenient means of suspension for the lamp.

We are aware that lamps and heaters have been made in which the fluid has been fed through a fibrous material for the purpose of developing vapors. We are also aware that many of the mechanical elements entering into our construction have been used in other and diderent structures for like purposes; but we are not aware and do not believe that a lamp of this character has been heretofore madein which so simple a construction has been able to produce so satisfactory results.

l. In a gasolene-gas lamp, a gas-chamber, a frusto-conical perforated developing vessel within this chamber tapering downward and IOO filled with a light porous substance as dereservoir and closed byaspring as described, scribed, the fluid-supply tank opening into anda link connecting the valve-operating dethegas-chambercentrally above thisl developvice and the cock-operating device, so that 15 ing vessel, a supply-cock between such tank both will move together, substantially as de- 5 and chamber, :md an air-valve opening into scribed.
